3,7-Inter-m-phenylene-3-oxa-4,5,6-trinor-13,14-didehydro-11-deoxy-PGE1

ABSTRACT

This invention comprises certain analogs of the prostaglandins in which the double bond between C-13 and C-14 is replaced by a triple bond. Also provided in this invention, are novel chemical processes and novel chemical intermediates useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.

The present application is a divisional application of Ser. No. 657,740, filed Feb. 13, 1976, now pending issuance as a United States Patent.

The present invention relates to prostaglandin analogs, for which the essential material constituting disclosure therefor is incorporated by reference here from Ser. No. 820,974, filed Aug. 1, 1977, which is a divisional application of Ser. No. 657,740.
